Читать книгу The Healthy Thyroid: What you can do to prevent and alleviate thyroid imbalance - Patsy Westcott - Страница 22

The main job of thyroid hormone is to regulate your metabolism – the rate of your body’s cell activity. It does this by activating mitochondria, the tiny cellular ‘powerhouses’ that produce energy. The process of metabolism – the word literally means ‘change’ – among other things, controls your appetite and maintains your body temperature, whatever the external environment.

Your metabolism determines the rate at which your cells burn oxygen, a process involved in every activity of life – from breathing and sleeping to eating, talking and moving around – as well as all the activities of your internal organs, such as the beating of your heart, the digesting of your food, the functioning of your reproductive organs and, most important of all, the working of your brain.
